Some people tweet about new Oracle patch set 188.8.131.52. I decided to check it too but I can't find it on MOS any more. Not only me as Tim Hall (@oraclebase) tweet about that situation too.
Anyway there is one important note on MOS - 1189783.1 - starting with patch set 184.108.40.206 new Oracle patch sets will be full installations of Oracle Software and patching out-of-place will be preferred one or even mandatory one in case of Grid Infrastructure.
I hope this note doesn't disappear from MOS like patch set and will be still valid after a few days.
Now I'm waiting for 220.127.116.11 to appear once again.
